Pressure Pipes

The selfit (Solvent Cement joint) pipes have one end self-socketed and the other and plain, which fits snugly without the use of couplers. The strong solvent cement joint is permanent and trouble-free.

Range

Selfit pipes are manufactured in the range of 40 mm to 315 mm diameters in 2.5, 4, 6, 8, 10 and 12.5 kgf/cm2 working pressure.

Advantage:

Selfit sockets are formed with high precision on specially developed sophisticated machines.

50% saving in installation time, as compared with plain ended pipes and loose couplers.

The number of joints is reduced by 50% resulting in substantial saving in labor costs.

The requirement of Solvent Cement for a pipeline is reduced by almost 50%.

Cost less than conventional plain ended pipes with loose couplers.

Eliminates the inconvenience of loose couplers, and reduction in inventory costs.

Plain pipes are available in 315 mm diameter in 2.5, 4, 6 and 10 kgf/cm2 working pressure.

Selfit pipes are supplied in standard length of 6 meters exclusive of the socket portion.

1. Note – The table is based on metric series of pipe dimensions given in ISO 161/1 in respect of pipe dimensions and ISO DIS 4422.

2. Note - The wall thickness of pipe is based on a safe working stress of 8.6 Map at 270C. The working pressure gets reduced at sustained higher temperatures. Occasional rise in temperature, as in summer, with concurrent corresponding reduction in temperature during nights has no deleterious effect on the working pressure of the pipes considering the total life of pipe.
